Abstract

La présente invention concerne des procédés et un appareil faisant qu'une mesure faite pour une automobile donnée par un détecteur donné soit sensiblement répétable en utilisant, soit le même détecteur d'un instant à l'autre, soit en utilisant un détecteur différent. Selon un mode de réalisation, pour déterminer les coefficients de normalisation, on mesure un ou plusieurs automobiles à sonde commune (102, 104), puis on normalise les sorties du détecteur ou des détecteurs (110) pour donner une sortie cohérente. Selon un autre mode de réalisation, pour déterminer les coefficients de normalisation, on mesure un ou plusieurs paramètres de fonctionnement ou de circuit des circuits des détecteurs, et on corrige les sorties des détecteurs des écarts affectant les paramètres mesurés. Selon un mode de réalisation, un amplificateur différentiel (208) multiplie la sortie du détecteur (204) par le coefficient de normalisation du premier ordre (206). Selon un autre mode de réalisation, un processeur de signal numérique (302) applique à la sortie du détecteur (204) les coefficients de normalisation.
